Runs Faster Whisper on your computer, then creates SRT files you can import. No source footage is uploaded by this page. Transcription accuracy varies by language.

Caption layout Burn subtitles into MP4 (requires FFmpeg libass)

Without burning, MP4 captions are selectable. One-word timing is estimated from caption durations, not speech-aligned.

Transcript-linked editing

Import SRT captions or the offline word-timed transcript first. Jump, correct text, or remove a chosen phrase across the whole timeline. Cuts ripple every track and remove intersecting captions; Undo restores them.

Review silence suggestions

Analyse the selected audio/video clip locally with FFmpeg. Suggestions are never applied automatically.

Track and mask moving regions

Select a video clip, pause at its first frame, then drag a rectangle directly on the preview. The local Windows processor follows that region using template matching and creates a new blurred/pixelated MP4. It is not semantic object removal.

Effect

No region selected

Replace selected clip with processed video (MP4 / WebM)

Inspect the entire processed result before publication. Mask tracking can fail during occlusions, fast motion or scene cuts.

Audio mixing

Gain and fades apply to audio clips and sound from videos. Values also affect the offline MP4 render.

Project backup

Manifest stores edit decisions, not source media. Reattach original files after reopening.

Original editor inspired by common non-linear editing workflows. No proprietary editing or voice models are copied. Voice Studio provides local voice recording, model render kits, timed captions and MIDI export. MP4 export runs with local FFmpeg using the downloadable Windows render kit. Browser WebM is a quick preview. Offline MP4 and automatic captions require separate local Windows render kits. AI transcription does not run inside the web page, and avatar generation or advanced visual effects are not included.
